Heat transfer to the basement with Climate Shield

[wwsmith111]

I have a new Eagle 338 rlts with Climate Shield. This unit provides heat to the holding tanks when the furnace is running. We keep it plugged in all the time when not in use. In the Winter we put in two small space heaters to keep it at about 50 degrees but don't run the furnace unless we are using it. I was wondering if anyone has checked to see how much heat is transferred through the floor into the basement area where the holding tanks are located. I have had several people tell me, including the dealer, that my holding tanks won't freeze up as long as I've got a space heater going inside. I bought a indoor/outdoor thermometer to check it this winter. I was going to drop the remote probe into the basement in between the holding tanks to see for myself just how cold it gets when it is 50 degrees inside the RV. I am going to winterize it just to be sure. We use it several times during the winter. It would be nice to say that I don't have to worry about it if it is say above 20 degrees or whatever the cutoff temp may be.
